I see "content: ".";

what does that do?

Have you got a link to the site? Quick tip......always test in firefox, not IE

The :after pseudo element is a CSS function for adding (and styling) content after a selector.

The content is the actual content to be placed after the selector. In this case, a period. Usually this is a handy technique for clearing floats in FF, without the need for additional markup (which is not semantic).

@Hyroz - a link would be really useful. Since you've also got images in your layout, it will be hard for us to debug if we're not seeing the same thing as you. (Otherwise upload a zip of your files).
